Have you explored sadomasochism? There are groups on fetlife that meet and may be open to a couple. The usual staple activities are bondage and flogging. Mix some pegging in if you like being more dominant. There are also more extreme kinks that your partner may be into (watersports, puke, fisting).

Ask him to try one of your fantasies. Genuine interest and enthusiasm make any sex so much hotter.

Everyone’s different and has different tastes. Same goes for the women, and I’d say it is generally hot to know and see what turns her on too. Make sure to communicate with your partner, and experiment if experiences are low on either side and see how you and they react. Show them if you like things, either by saying it directly or reacting accordingly. Same goes of course for the opposite experience as well. If you’re into pleasing / being submissive then that can be hot, assuming you look like you’re enjoying it and not just work it like you have to. You riding in various positions can also be a good way to please while maybe being a little more dominant, since it is usually the guys doing most of the penetrative work. As for sucking dick, depending on how submissive you are of course throatjobs / facefucks are very pleasurable, but certainly not easy or for everyone due to gag reflexes. Can get dirty when unskilled, but there’s also people who are into that part (pukejob).

The more interested and horny you are, the better. A real man likes to know when his lady is feeling frisky. Ask him what he likes, too. Every man is different.

Rusty trombones are sexy, especially after taco night.
